Trump Tariff Legality Battle Leaves Markets Confused

Published / Last Updated on 30/05/2025

Overnight in the US, the Appeals Court has temporarily overruled the Court of International Trade’s ruling that emergency laws introduced by the White House to impose trade tariffs on most of the World was illegal.

This means, and to quote the Appeals Court spokesperson, “the tariffs can remain for the time being”.

What’s Going On?

On Wednesday, the Court of International Trade ruled that emergency trade tariffs imposed by the US around the World were outside President Trump’s jurisdiction.  The ruling was raised from two legal challenges that had been mounted by a collectrive of some government departments as well as another by the Liberty Justtice Centre.

  • Stock markets around the World climbed with hopes of tariff removal.
  • The ruling was criticised by Trump supporters in that “it is not for unelected judges to decide how to properly address a national emergency”.
  • The counter this, the Attorney General of New York, Letitia James was quoted as saying: ”The law is clear, no president has the power to single handedly increase taxes whenever they like”.
  • Overnight, the Appeals Court overruled the Court of International Trade, so tariffs are back on, for now.

Comment

Whilst we are not politicans, the legal battle to come will affect markets and therefore your pensions and investments.

We are also not US lawyers, but we have to say, whilst we understand Mr Trump's desire to balance trade deficits to protect US trade, the economy and jobs, in a democracy, we would have expected any changes in taxes to go through the usual channels of Congress and the Senate rather than emergency powers.

That said, President Trump does have majority, and he would appear a formibale oponent, so we do not expect tariffs to disappear.  What we expect is yet more stock market volatility.
